摘要:

近年来，基于故障分量的保护得到了广泛的应用。但大量的文献多是从应用角度讨论故障分量、工频变化量、正序故障分量、负序故障分量、零序故障分量、暂态故障分量、突变量等概念。该文给出了这些概念的严格定义，并且讨论了它们的特征。概念的定义、特征的讨论，有助于理解这些概念，有助于提高基于故障分量保护的研究和运行水平。

关键词: 故障分量工频变化量突变量正序故障分量暂态故障分量

Abstract:

In recent years, protection relaying based on fault component is used widely. But a large number of literatures on this subject mostly discuss the concept related to fault components from the view of application, like Power-frequency Variation, break variable,positive sequence fault components,fault-generated transients, etc. This paper discusses the characteristics of fault component using the strictly defined concept. The viewpoint of this paper contributes to understanding of these concepts and to improving research and operation level.

Key words: fault components power-frequency variation break variable positive sequence fault components transients fault compoment
